JavaScript - Help With Compound Css Selectors Creating Image Rollover To Fade-fadeout
I've got a <ul> w/ 6 <li> items and CSS to make them 104x228 side blocks, which hold 2 images, one on top of the other. The 6 rows of images look like this:
X X X X X X X X X X This is what I want: The top row of images to be opacity:0 (or hidden), and then when you mouseover the bottom images, the top images come to 100 opacity. When you mouseout, the opacity is back to 0. Here's the HTML and CSS: Code: <ul class="carz"> <li><img src="img/impreza2.jpg" class="imgtophidden"/><img src="img/impreza.jpg" /></li> <li><img src="img/wrx.jpg" class="imgtophidden"/><img src="img/wrx.jpg" /></li> <li><img src="img/legacy2.jpg" class="imgtophidden"/><img src="img/legacy.jpg" />/li> <li><img src="img/outback2.jpg" class="imgtophidden"/><img src="img/outback.jpg" /></li> <li><img src="img/forester2.jpg" class="imgtophidden"/><img src="img/forester.jpg" /></li> <li><img src="img/tribeca2.jpg" class="imgtophidden"/><img src="img/tribeca.jpg" /></li> </ul> The classes are like so: Code: .imgtophidden {
opacity: 0;
}
.imgtop {
opacity: 100;
}
I am new to jQuery coding (but loving learning) and I want to figure out: how do I make this in jQuery? Here's what I have so far: Code: $(function() {
$("ul.carz li").hover(function() {
$(this).find('img.imgtophidden').addClass('imgtop')
} , function() {
$(this).find('img.imgtop').addClass('imgtophidden')
});
});
Similar TutorialsHi Guys, I hope this is a good place for me to post a question. I saw some responses referring to this and I hope as a newcomer my question is not booed! :) I am attempting to compound a rollover effect I have currently working at this page. The 4 numbered buttons make the larger image next to it change upon on roll over. I would like the buttons themselves also to have a rollover state. In my code below, I simply added a space in my JS script after the portion of the script that I know is working ends and added the newer code referring to 71, or rollimg71 (an arbitrary number). The area that says //button rollover effect is the code I added that does not break the site but does not work correctly. My JS <code> // JavaScript Document //gallery rollover effect if (document.images) { image0 = new Image; image1 = new Image; image2 = new Image; image3 = new Image; image0.src = 'ectonymimages/newsletter1.jpg'; image1.src = 'ectonymimages/newsletter2.jpg'; image2.src = 'ectonymimages/newsletter3.jpg'; image3.src = 'ectonymimages/newsletter4.jpg'; } else { image0 = ''; image1 = ''; image2 = ''; image3 = ''; document.rollimg = ''; } //button rollover effect if (document.images) { image71a = new Image; image71b = new Image; image71a.src = 'ectonymimages/newsletter1_link.gif'; image71b.src = 'ectonymimages/newsletter1_linkselected.gif'; } else { image71a = ''; image71b = ''; document.rollimg71 = ''; } </code> My HTML <code> <div style="float:left; padding:10px 0 0 25px;"> <span onmouseover="document.rollimg.src=image0.src;" onmouseover="document.rollimg71.src=image71b.src;" onmouseout="document.rollimg71.src=image71a.src;"><img src="ectonymimages/newsletter1_link.gif" alt="Newsletter 1 Button" name="rollimg71"/></span> <br /><br /><br /> <span onmouseover="document.rollimg.src=image1.src;"><img src="ectonymimages/newsletter2_link.gif" alt="Newsletter 2 Button" /></span> <br /><br /><br /> <span onmouseover="document.rollimg.src=image2.src;"><img src="ectonymimages/newsletter3_link.gif" alt="Newsletter 3 Button" /></span> <br /><br /><br /> <span onmouseover="document.rollimg.src=image3.src;"><img src="ectonymimages/newsletter4_link.gif" alt="Newsletter 4 Button" /></span> </div> <div style="float:right; padding-right:50px;"> <img src="ectonymimages/newsletter1.jpg" align="Newsletter Example" name="rollimg"/> </div> </code> Right now, my HTML only attempts to affect the first button, but I hope to have it affecting all 4 buttons. (Presumably if I keep this same format, they would be rollimg72, rollimg73, and rollimg74 added somewhere in the JS) Further, I'll also compound an onclick function, for both the buttons and the larger images, that will open a pop up HTML window. So, my priorities are that I'd love for the buttons themselves to have a rollover effect and then also an onclick function that opens a link in a new window in addition to the rollover effect currently being used. *If I mouse over a numbered button, that numbered button changes. *If I mouse over a numbered button, depending on the numbered button doing the affecting, a larger image is displayed next to it that changes on rollover. (This step already works correctly.) *If I click on a numbered button, 1 of 4 links would open. If I click on the larger image that changes, 1 of 4 links would open. If you've read this far, thank you in advance! Heh heh, this is the 2nd time I've typed this, as the forum logged me out and deleted my entire post when I clicked "preview". Any help is much appreciated! Gentlepeople, I ask your assistance. -Marcus OK, I want several of my images on my webpage to change when the user hovers over the graphic. I created the js and it works fine. However, now all of my (linked) images change when I hover over them. I know what's causing this ( the Code: ( document.images[i].parentNode.tagName =="A" ) part), but not sure what the best way to fix it would be. Any advice? window.onload=rolloverInit; function rolloverInit( ) { for ( var i=0; i<document.images.length; i++) { if ( document.images[i].parentNode.tagName =="A" ) { setupRollover( document.images[i]); } } } function setupRollover(thisImage) { thisImage.outImage =new Image(); thisImage.outImage.src= thisImage.src; thisImage.onmouseout=function() { this.src=this.outImage.src; } thisImage.overImage = new Image(); thisImage.overImage.src= "images/" + thisImage.id + "_on.jpg"; thisImage.onmouseover= function( ) { this.src=this.overImage.src; } } [/CODE] This is a really awesome script that I'm sure all of you can put to use if you haven't yet heard of it. However, I'm trying to get it to fade a background image on my css styled navigation for my a:hover. Here is the script with a little simple tutorial on how to set it up: http://bavotasan.com/tutorials/creat...r-fade-effect/ My only other knowledge is in PHP, so after about 2 hours of fail in this client-side language, I decided it was about time I should post where some experienced people can help. I really appreciate all time you spend on this, and don't think it will take a moderate Javascript programmer very long. This is the link to my site so far: http://matt.mw/help-request You can see the script working as it is on my little yellow MW logo on the right side of the navigation. So in my scenario, I am looking to fade button.png to button-hover.png (both repeating on the x axis). Any ideas? Hi, I am looking for a script which could do picture animation like in this page But there is other problem: When you put your mouse on them, they appear colored. I need that this appearing action would take 5 seconds. 5 sek. to become colored, 5 sek. to become grey when you put away your mouse. If you need more info, ask.. Thanks a lot. How can I add fadeIn and fadeOut with a duration that I can set/adjust to this javascript? The site is using Zencart and the the Image Hover effect comes from the Image Handler 2 Add-on. Thank you in advance for your help. Your time and attention in helping me with this is greatly appreciated.

Is it possible to have a form's textarea background image fadeout to an alternate bg image, when that textarea is selected (by clicking the textarea or tabbing to it)? I've never seen this done before, but I'd really like to do it..
Hey guys, Lookin' for a little help, not sure if it can even be done? hopefully someone has the answer. I'm trying to design myself an online portfolio; here's what I got so far... http://www.gregorymstevens.com/testsite/site.html As you can see my navigation is represented by each bird on the tree (every bird is a link), when you rollver one of the green birds they turn white, however, I am looking to not only have the green bird rollver to white but ALSO have the "choose a" image on the bottom right change to the corresponding page. For instance, when the mouse rolls over a bird-- this image: will turn into this image: while maintaining the original "white bird" rollover. Hopefully I'm explaining this correctly -- Any help greatly appreciated! I've been looking for a way to fade a selection of images in on load while keeping their background present until they fade in. similar to whats been used on this site: http://inventorystudio.co.uk/ thought this would be relatively simple but seems to be harder than i expected. any suggestions? I have this code... I want to be able to make each image fade from one to the other. Like this... http://www.dynamicdrive.com/dynamici...nslideshow.htm Is there a way to do that with this code? Code:
<script type="text/javascript">
// Simple Javascript Time based Image Swap
var Pics = new Array();
var counter = 0;
// Use this section to change the image paths
function LoadImages()
{
Pics[1] = new Image();
Pics[1].src = "images/pic1.jpg";
Pics[2] = new Image();
Pics[2].src = "images/pic2.jpg";
Pics[3] = new Image();
Pics[3].src = "images/pic3.jpg";
Pics[4] = new Image();
Pics[4].src = "images/pic4.jpg";
Pics[5] = new Image();
Pics[5].src = "images/pic5.jpg";
Pics[6] = new Image();
Pics[6].src = "images/pic6.jpg";
Pics[7] = new Image();
Pics[7].src = "images/pic7.jpg";
Pics[8] = new Image();
Pics[8].src = "images/pic8.jpg";
Pics[9] = new Image();
Pics[9].src = "images/pic9.jpg";
Pics[10] = new Image();
Pics[10].src = "images/pic10.jpg";
Pics[11] = new Image();
Pics[11].src = "images/pic11.jpg";

Pics[16] = new Image();
Pics[16].src = "images/pic16.jpg";
Pics[17] = new Image();
Pics[17].src = "images/pic17.jpg";
document.pic1.src = Pics[1].src;
}
//Time in miliseconds
function timedImage()

counter ++
if (counter > 17) {
counter = 1;
}
document.pic1.src = Pics[counter].src;
t=setTimeout("timedImage()",5000);
}

Hi! I'm wondering if somebody here could help me please. I'm trying to develope the image slideshow using PHP and JavaScript. The idea is that the PHP file gets random images from the folder, i'm using session to prevent repeating the same image and then JavaScript generates the fade slideshow using that PHP file. I've come up with the solution to use two img tags in the HTML page, so JavaScript then swap them around and play with opacity, but unfortunately couldn't make it work. Everything I have tried in JavaScript didn't work properly. I'd be grateful for any help and advice guys. Thank you. My PHP code: PHP Code: <?php class images { var $images = Array(); var $imgDir = 'images/'; function getImages() { $images = Array(); if ($dir = opendir($this->imgDir)) { while(($file = readdir($dir)) !== false) { if(preg_match('#(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)#i', $file)) $images[] = $file; } closedir($dir); } return $images; } function getNextImage() { if (($images = $this->getImages()) !== false) { session_start(); if (!isset($_SESSION['image'], $images[$_SESSION['image']])) { $index = mt_rand(0, count($images)-1); } else { $index = $_SESSION['image'] == count($images)-1 ? 0 : $_SESSION['image']+1; } $_SESSION['image'] = $index; return $images[$index]; } return false; } function outputImage() { if (($file = $this->getNextImage()) !== false) { header('Cache-Control: no-cache, must-revalidate'); // HTTP/1.1 header('Expires: Wed, 9 Dec 1981 07:00:00 GMT'); // Date in the past header('Content-type: image/jpg'); readfile($this->imgDir.$file); exit(); } } } $img = new images(); $img->outputImage(); ?> My HTML page: Code: <html> <head> <title>Images</title> <link rel="stylesheet" type="text/css" href="css/style.css" /> <script type="text/javascript" src="javascript/slideshow2.js" language="javascript"></script> </head> <body onload="startSlideShow();"> <h1>Images</h1> <div id="imageWrap"> <div id="images"> <img id="sampleImgFade" src="images.php" alt="images" style="filter:progid:DXImageTransform.Microsoft.alpha(opacity=0);-moz-opacity:0;-khtml-opacity:0;" width="800" height="600" onload="coverLoaded(this);" /> <img id="sampleImg" src="images.php" width="800" height="600" alt="images" onload="mainLoaded();" /> </div> </div> </body> </html> CSS code: Code: #imageWrap {

Dear all, I have been trying to replicate a cool javascript effect that appears here. See the funky images fading in when hovering with mouse? I want that ;-) By using Firebug I think I have narrowed down the code needed to: Code: <div id="main" class="clearafter">
<div class="inner clearafter">
<div class="columns clearafter">
<div class="project hovers column" style="border-color: rgb(255, 255, 255); cursor: pointer; background-color: rgb(255, 255, 255);">
<a href="http://mountfolly.co.uk" class="image">
<img width="274" height="137" alt="project" src="/images/41_project.jpg" class="screenshot">
<img width="274" height="137" alt="project" src="/images/7_project.jpg" class="text" style="opacity: 0; display: inline;">
</a>
<h3>Text and titles etc...</h3>
<p>etc etc etc...</p>
</div>
<div style="border-color: rgb(255, 255, 255); cursor: pointer; background-color: rgb(255, 255, 255);" class="project hovers column"></div>
</div>
</div>
</div>
<script type="text/javascript" src="/javascript/global.js"></script>
and this (which I put into a javascript file called global.js): Code: /* project listings */
// to deal with IEs opacity idiocy
$(function() {
$('.project.hovers .text').css({opacity: 0}).show();
$('.project.hovers').css({cursor: 'pointer'}).click(function() {
location.href = $('h3 > a', this).attr('href');
});
});
$('.project.hovers').hover(
function () {
$('.text',this).stop().fadeTo('100',1);
$(this).stop().animate({borderTopColor: '#E9E9E9', borderRightColor: '#E9E9E9', borderBottomColor: '#E9E9E9', borderLeftColor: '#E9E9E9', backgroundColor: '#EEE' }, 100)
},
function () {
$('.text',this).stop().fadeTo(1000,0);
$(this).stop().animate({borderTopColor: '#FFF', borderRightColor: '#FFF', borderBottomColor: '#FFF', borderLeftColor: '#FFF', backgroundColor: '#FFF' }, 1000)
}
);
But when I re-create the files (index.html, global.js, and replacement images) all I get is this. No hover effect... Any ideas what is missing? Would appreciate some help. Thanks, Wysiwyger PS: If you fancy a laugh, check these out Hi, I'm building a website which uses javascript to cycle through and fade images in the header portion of each web page. The javascipt os located in an external file and called via the master page. Here is the code in the content.js file which specifies where the images are located: Code: // create array of images
var CyclingImages = new Array("header/images/tankimage1.gif",
"header/images/tankimage2.gif",
"header/images/tankimage3.gif",
"header/images/tankimage4.gif")
Here is the code in the master page which finds the javascript: Code: <script language="javascript" src="<%= Page.ResolveUrl("~/content/content.js") %>" type="text/javascript"></script>
Here is the function call in the masterpage to fade and cycle the images: Code: <body onload="FadeAndCycleImages()"> Here is the code in the masterpage which references the cycling images: Code: <span class="fadingimages">
<img src="<%= Page.ResolveUrl("header/images/tankimage1.gif") %>" width="142" height="124" title="" alt="" name="cyclingimage" />
</span>
Each webpage loads the masterpage. If the webpage is located at the root of the project, the cycle and fade functionality works great. When I start to place some of the webpages in separate folders - which I need to do - the cycling and fading functionality breaks down, meaning the images cannot be found. The image place holder is there with the standard red "x" in the upper left. I have done a lot of research and tried many approaches to try to resolve this issue, but with no success. The root of the problem seems to lie in the fact that I cannot apply Page.ResolveUrl within the content.js file. Any suggestions would be greatly appreciated. Thank you, petela Hi everyone. I'm brand new to this forum and in need of some help. If you've got a free minute and are interested in helping the clueless I've got one for you. I'm trying to form a script and the appropriate calls to fade-in some text on the event of an image mouseover. Here is what I'm working with: Code: <html>
<head>
<script type="text/javascript">
function setOpacity(level) {
element.style.opacity = level;
element.style.filter = "alpha(opacity=" + (level * 100) + ");";
}
var duration = 1000;
var steps = 20;
var delay = 5000;
function fadeIn() {
for (i = 0; i <= 1; i += (1 / steps)) {
setOpacity(" + i + "), i * duration;
}
}
</script>
</head>
<body>
<p id="text" style="filter:alpha(opacity=0);opacity:0.5">
This is the text.
</p>
<img name="image" src="pic.jpg" onmouseover="javascript:fadeIn(document.getElementById('text'))" />
</body>

I know there are problems with this. It looks wonky to me and I don't even know what I'm doing. It's a mashup of some code I found somewhere and my own bad guesses at how to fill in the gaps. Any tips on how I can bring this together? Thanks so much for reading this far. I appreciate your time. I've been trying to figure this out for days.. I just found a script that Old Pedant made which is close to what i need: http://www.clearviewarts.com/fadeBigDemo.html But two concerns: 1. how can i have it so when i click the thumbnail, it fades in a different image (rather than just a larger version of the thumbnail)? 2. how can i have it fade in and out from simply hovering over the thumbnail (rather than clicking it)? Your help would be greatly appreciated.. Hello, I'm learning javascript, and was wondering if it was Possible to have buttons/links that you click, the whole page fades out, and then fade's in, with different stuff. here are my ideas for just changing the stuff Text: 1. having a javascript src file to start, and then when the button is clicked, that is formatted to white, the text layer is moved down, and a new javascript file is loaded? 2.variables? any help would be appreciated! Thanks, Cookies, whatever this forum gives out, you may receive! Hi everyone, I'm new on this forum. I really need help in coding an part of my website. I want to make the logo background image fade to another background image on hover. Here is the code I have until now: Code: #logo
{margin-top:0px;
margin-bottom:0px;
margin-left:auto;
margin-right:auto;
width:600px;
height:515px;}
#logo h1
{display:block;
background:url(img/logo.jpg) no-repeat;
width:600px;
height:515px;
text-indent:-10000px;
margin:0px;}
#logo h1 a
{display:block;
width:100%;
height:100%;}
#logo h1 a:hover
{background:url(img/logo.jpg) no-repeat 0px -515px;}
I want the background:url(img/logo.jpg) no-repeat; to fade to {background:url(img/logo.jpg) no-repeat 0px -515px;}. I haven't found any tutorial which explains how to do that properly. I'd be really greatful if you could help me. Thank you very much, Alex Hello and thanks for the help. I'm no expert by any means, and I have no idea what the problem could be. Internet Explorer crops my images on my image fade, but Chrome and Safari view it just fine. the website is www.pisanchynproductions.com If you open it in IE and Chrome you can see Chrome shows image fadeshow fine, and IE crops the images. For the record, I don't want the images cropped. The problem must be in here somewhere. Code: var fadeimages=new Array()

I wish i knew more so I could realized how dumb this question was. http://www.javascriptkit.com/javatut...rnalphp2.shtml Anyone have a decent way of adding a fade affect to this script? Hi, I'm have set up a gallery site, pretty standard stuff with thumbnails to the right and big image to the left. I would like to add a fade in on the big image when the thumbnail is clicked and don't really know how to implement it. The big images are contained in a div called <#left> while the thumbs are within a div called <div class="gallery"> I have searched Google and these forums for a solution but haven't had any luck...can anyone help me out with this? Thanks J Hi there, I found this thread on the forum its from a few years back but the code works, but I can't seem to get the image that appears as you rollover the button to display in the correct place. I'm not sure if its because I'm using tables within tables? Should I recode in divs? Any help is greatly appreciated!! http://www.codingforums.com/archive/...p/t-95847.html |
